Yonhap News: The Korean Society of Superconductivity and Cryogenics has concluded, after experiments, that LK-99 is not a superconductor. It's basically in a state of complete uncertainty right now, with labs everywhere saying "I've got solid evidence that this thing isn't a superconductor", but then there are places that say, "I've repeated the experiments according to the papers that are capable of superconducting".

That sounds like my way of treating the tea - my other long-lasting way of consuming caffeine - without adding anything and keeping it hot

I've been thinking about it for a while, and I really should take your advice about which brews it for less time: because I'm using Illy's ground coffee in my office right now - it's the coarseness that can put in the coffee machine to make espresso, not the coarser one that I grind in my coffee grinder at home. Damn my stomach Because I'm living in a sub-tropical city - there's 30℃ nearly every day. And the ac in our office needs time to chill the room down. My way to drink sometimes is only coffee without anything for emergencies (which means I got insomnia and couldn't find spirits liquid sleeping pills last night), or putting the coconut milk powder for chill. My way to make the cold brew is to put the room temp water in it and then put it in the fridge.

9728, reporting!

Please don't drink the cold brewed coffee you put in the fridge for more than one night. I have a habit that at the end of the day and putting water and coffee in the French Press pot and then putting it in the fridge at our office. The next morning, I can have an ice-cold cup of cold brew coffee. As it turned out, yesterday I had to go out to visit our client with our group at short notice and was out of the office until late at night before I could leave work. So, the cold brew sat in the fridge for two nights. I just drank this half an hour ago. I've already made three trips to the restroom because of the huge amount of caffeine. It feels like there's a... well... some revolutions in my stomach.

My own recipe for this would skip adding starch water mix and no white vinegar. And I recommend chopping a little bit of spring onion before cooking (you can also snip it with scissors) and then throwing it in the pan and tossing it around before it's about to come out of the pan on the plate.

Good day, your Highness. Seems like you have a pleasant day? Wait a second. Please, mind your manners!

"Huston, we are not alone"

I just tried auto-driving controlled by ai through the radars and other sensors on my dad's new car this morning to work. Have to say it feels really weird that "someone" is twisting your steering wheel. And then because it's based entirely on its own measurements, makes lane changes, and other maneuvers are carried out quite decisively - even a bit scary. In my father's words, it's like a 20-year veteran driver being late for work.

Although our forum has many steve, but the one I post was from SYSU What they found is near 80K in high pressure. Link from SYSU themselves: https://www.sysu.edu.cn/sysuen/info/1711/36032.htm Link from Nature without paywall: https://www.nature.com/articles/s42005-023-01155-7

I saw some guys from different labs and unis on Zhihu (Chinese Quora) who said they tried several times to reproduce the experiment. But the results are all failures. The thing is, despite my extremely shallow understanding of physics and chemistry, this article of theirs feels a bit like some sort of medieval alchemy to me. Then the whole article gave me the impression that "the researchers were too happy with the results to make the article out in the shortest time they can". I'm waiting for a more formal peer-reviewed academic paper.

Jia Hongguang(贾宏光), founder and CEO of Jilin Changguang Satellite: Jinlin-1 satellite constellation will achieve 138 satellites in orbit by the end of this year and have the ability to revisit any point on the globe within 10 minutes. By the end of 2025, the number of satellites in orbit will increase to 300. The company also plans to further expand its business into the field of rocket development, in order to break the "bottleneck" of insufficient launch capacity faced by China's commercial spaceflight. Report link: http://news.haiwainet.cn/n/2023/0731/c3541093-32637099.html But the interesting part to me is, the report describes a "science exhibition area" in their factory where you can see the entire satellite production plant in progress through a large glass window: "To our reporter's surprise, in the popular science exhibition area, through the clean, fully enclosed large glass windows, you can overlook the satellite operations workshop. Where the layout of the furnishings, equipment, and personnel on-site operations briefly. In order to help visitors better understand the relevant knowledge, large glass windows next to the wall, but also posted on the workshop process involved in the specific introduction and explanation, some also with a number of high-definition flow charts." Now you know a tourist attraction that would surprise even the locals - "How did you know this place was so interesting".

Need to say that it’s pretty hot right now in southern China. Some kind of “good news” is since 17 July a typhoon has passed by Wenchang, followed by two typhoons last week and this week, both of which have brought a lot of rainy weather to the costal part of China.

Thanks that guy for putting the question I always want to ask since I know the words “aliens” and “UFO”

Wait, your short "lovely" rocket design is... really serious? Qu Wei(曲伟), member of PCC, and researcher of 11 Academy of CASC: GW (Guowang,国网) satellite constellation program is expected to launch 13000 satellites. "The altitude of GW's orbits will be lower than American's Starlink. This will, to a considerable extent, avoid overlaps and collisions and ensure safe distances. Lower-orbit satellites have the advantages of being highly resistant to destruction, flexible in deployment, having a large transmission capacity, and being unaffected by terrain."

An international foreign trade company next door to us has a cat. He sometimes steps out to inspect his loyal domain (which is our floor). And sometimes, his faithful people - the female colleagues of our company - would come to have an audience with him. As always, his Highness kept acting like he didn't really care about his people. Until just now when I passed by a beauty company next door to them - and the children of their company's clients were kidnapping our lord.

The universe is so big that if someone says we are the only civilization in this universe, I will never believe it. But I also won't buy such simply wasting time conspiracy theories. As for the balloon, if our American friends who study China can speak more Chinese than "nihao", "Taiji" and "gongxifacai", have some academic searching skills, and are not so biased, it is not difficult at all to obtain cross-checked facts within an hour.

The low-temperature bursting test on the common bulkhead propellant tanks for CZ-10 has been completed. "...Successively overcome the propellant tank high-precision pressure control, overpressure explosion, and other difficult problems. To achieve the upper and lower fuel tank hydrogen, nitrogen, and helium three kinds of pressurized gas free switching. Strongly guarantee the reliable operation of the test system, and ultimately the successful completion of the four low-temperature static tests and one low-temperature bursting test." "In addition, in order to ensure the safety of personnel, important equipment, and facilities at the test site, an exceptionally reliable flame-retardant explosion-proof blanket designed independently by 'our institute' (Original word. It's 101 Institue of 6th Academy of CASC, aka Beijing Aerospace Testing Technology Research Institue) was used during the test. Which effectively blocked the explosion shock wave generated during the blasting process and the damage caused by the high-speed fragmentation of the propellant tank cutting and provided a safe and reliable test environment for the researcher."

I have the original Chinese link. But I just realized I just shared so many full Chinese link so I randomly found someone who can put this clearly and objectively…

Meanwhile, Sun Yat-sen University found 80K one: https://www.gamingdeputy.com/chinese-scientists-took-the-lead-in-independent-discoverythe-new-high-temperature-superconductor-only-needs-192℃-fast-technology-technology-changes-the-future/ Nature: https://www.nature.com/articles/s41586-023-06408-7

But the thing is, just to move a set of metal smelting production lines from Earth to the Moon as well would require quite a bit of cost - and just for the use on the moon. Not to mention if it's a rare earth resources smelting line on the moon. That really needs the whole country and try their best to do that. I think, current scientific progress on Earth still needs to be developed further to be worthy of such 'at any cost' approach to resource exploitation.
